I wish it was just the things I buy. All my Ebay sales and purchases get confirmation to my Google email, all bank reports come via email, and my doctor too uses a service to send my prescriptions to my gmail address.

Still, the amount of personal information available for mining to Google and others is plain scary: I've seen with these eyes lawyers sending photos of sensitive documentation via Facebook or Whatsapp; that's even beyond stupid.
